Title: Conceptual design of a sapphire loaded coupler for superconducting radio-frequency 1.3 GHz cavities

This paper explores a hybrid mode rf structure that served as a superconducting radio-frequency coupler. This application achieves a reflection S(1,1) varying from 0 to -30 db and delivers cw power at 7 KW. The coupler has good thermal isolation between the 2 and 300 K sections due to vacuum separation. Only one single hybrid mode can propagate through each section, and no higher order mode is coupled. The analytical and numerical analysis for this coupler is given and the design is optimized. As a result, the coupling mechanism to the cavity is also discussed.
